In this modern world everywhere we can see each and every individual either with an computer or mobile phone, this may make many works simpler, time saving, etc but on the other side there is also certain ill effects, among that one of the major problem that is increasing silently is “Computer Vision Syndrome”
Research shows that between 50% and 90% of people who work at a computer screen have at least some symptoms. According to the US National Institute for Occupational Safety and Health, computer vision syndrome affects about 90% of the people who spend three hours or more a day at a computer.[2] Another study in Malaysia was conducted on 795 university students aged between 18 and 25. The students experienced headaches along with eyestrain, with 89.9% of the students surveyed feeling any type of symptom of CVS.[3] Americans spend an average of 8 hours a day in front of a screen, whether that be a television screen, phone/tablet, or a computer screen[4][5]. This has increased the prevalence of individuals affected by computer vision syndrome.
Working adults aren't the only affected. Kids who stare at tablets or use computers during the day at school can have issues, too, especially if the lighting and their posture are less than ideal. It is not an single problem but it is a group of problems associated with it and it may also vary from each individual.
